There’s nothing wrong with cheap. I eat cheap. I wear cheap. I make cheap jokes. And for the longest time, Jaben shipped mainly cheap amps to my cohort: the masses, God bless ‘em. But Jaben have gotten off that kick. They’ll ring the charity bells in another season. Today is the day of the Porta Tube+ valve headphone amp/DAC for your iPad/Mac, a delightful machine for bourgeois ears, and sound fit for a king.
